I think the letter shows a sincere attempt to make amends.
If I were a Japanese American, I might have the following reactions:
The memories of internment still make me sad and angry. But I am happy that the president himself has admitted "that serious injustices were done to Japanese Americans during World War II." The president’s apology is a sincere effort to heal the emotional scars of the Japanese American community.
The president’s apology doesn't undo the damage that was done. But the lines "We must learn from the past" and "we can guarantee a future with liberty and justice" give me hope that no other ethnic group will be targeted in that way again.
According to the Oxford dictionary, Fascism tends to include a belief in the supremacy of one national or ethnic group, a contempt for democracy, an insistence on obedience to a powerful leader, and a strong demagogic approach.
